What are the working principles and characteristics of clean sheds?
1. Working principle of clean sheds:
The clean shed material is made of stainless steel and iron square tube sprayed plastic as the frame, and uses fan filter unit FFU for air supply. It is surrounded by anti-static curtains or organic glass, and the top is covered with cold plates or stainless steel plates to form a relatively closed area. The internal purification level can reach 100-300000; it is especially suitable for areas with high local purification level requirements in the workshop, such as assembly line work areas. High-precision product assembly area.
2. Characteristics of clean sheds:
1. Assembled structure design, easy installation, greatly shortened delivery cycle;
2. Easy to move, suitable for building small clean areas;
3. Modular structure, easy to improve purification level, strong scalability, and high reuse value;
4. Compared with the ultra-clean workbench, the internal available effective space is large; compared with the traditional clean room, it has low cost, fast construction, and no restrictions on floor height.
3. Conventional configuration of clean shed
l Frame: Made of stainless steel or iron square tube sprayed with plastic, stable, beautiful, rust-free and dust-free;
l Anti-static curtain: good anti-static effect, high transparency, clear grid, good flexibility, no deformation, not easy to age;
l Dust-proof and anti-static;
l The top cover of the clean room is made of cold-rolled steel plate electrostatic sprayed with plastic;
l The interior uses a special purification lamp for the clean room, which does not produce dust;
l Fan filter unit FFU: It uses a low-noise centrifugal fan with long life, low noise, maintenance-free, low vibration and adjustable speed. Among them, the high-efficiency filter (HEPA) is set at the end of the fan air supply unit. HEPA has the characteristics of low initial resistance, large capacity, high filtration effect, long service life and easy replacement.
